Stubborn and ardent clinging to one's opinion is the best proof of stupidity.
Bordeaux, France
I study myself more than any other subject. That is my metaphysics; that is my physics.
Every man carries the entire form of the human condition within him.
I do not speak the minds of others except to speak my own mind better.
If your mind is empty, it is always ready for anything, it is open to everything.
The most dangerous worldview is the worldview of those who have not viewed the world.
The greater the ignorance the greater the dogmatism.
